SPECIFICATION forming part of Letters Patent N o. 608,478, dated August 2, 1898.

Application led October 25, 1897, Serial No. 656 ,268. (No model.)

To all whom, it may concern:

Be it known that I, HERBERT S. P ULLMAN, of Waterbury, in the county of A New Haven and Stateof Connecticut, have invented a new Improvementin Bicycle-Bells; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

My invention relates to an improvement in that class of small portable bells primarily designed to be used upon bicycles, the obj ect being to produce a simple, light, durable, and effective bell.V

With these ends in view :my invention consists in a bell having certain details of construction and combinations of parts, as will be hereinafter described, .and pointed out in the claims.

In carrying out my invention I employ a sheet-metal carrier A, having straight sides and slightly-rounded ends and formed with a central circular opening A', two striker-lug slots A2 A2, longitudinally arranged on opposite sides ofthe opening A', and with four strap-openings vA2, arranged in pairs and located on opposite sides of the said striker-lug slots A2. Upon the upper faces of the ends of blanks to the action of dies which enter the upper faces of the blanks and shear the same, so as to form the lugs in an operation of a shearing character, which is not carried far enough to detach the lugs from the blanks, the upper facesof the strikers having recesses corresponding exactly in dimensions to the depending lugs produced as described. The said strikers are held against lateral displacement by means of transversely arranged sheet-metal straps C C, the arms of which are shouldered and formed with retainingfingers c c, which are passed through the openings A2 in the carrier-plate and bent inward, as shown in Fig. 9, whereby the straps are firmly secured in place. The upper portions or reaches of the straps stand, however, sufficiently above the upperv faces of the strikers to receive beneath them the ends of a longitudinally -bowed friction spring D, having acentral opening D', which adapts it to be passed over the 'gong-stud E, the said spring being placed under tension by the hub F of the gong F', which is removably connected with the said stud through the said hub in the usual manner. y The ends of the spring are longitudinally slotted,so as to form at each endV two spring-iingers D2 D2, upturned at their ends, and a shorter intermediate' spring-finger D3, turned downward at its end, but set above the other lingers. The fingers D2 of the spring bear upon the upper faces of the strikers, while the intermediate fingers D3 of thespring engage with the under faces of the straps and assist inA keeping the ends of thespring un'dertension and forcing the fingers D2 D2 into closer contact with the upper faces of the strikers. However, the number of lingers formed at the ends of the IOO friction-spring and the particular mode of bending them maybe varied; butI prefer to form a plurality ot fingers at the ends of the spring.

It will be readily understood from the Ieregoing description that the strikers are free to reciprocate under the restraint of the trietion-s1nring within the limits allowed by the length of the slots A2 in the carrier. t will also be understood that their action is a rebounding action-that is to say, that under the action of centrifugal torce due to the rotation of the carrier they will be thrown outward, so as to strike the inwardly-projeeting striking-lu g F2 of the gong, by which lu g they will be forced inward, so as to pass the same.

The carrier is mounted for rotation coneentrically with the gong by being staked in the usual manner upon the upper end of a tubular pinion G, which rotates upon the lowerend of the gongstud E as upon a center. The pinion G is meshed into by a wheel II, turning upon a stud II', mounted in the shallow cup-like circular base Ict the bell. The said wheel II is itseli' provided with a pinion Iig, which is meshed into by a segmental rack J, formed upon the inner end of the operating-leverJ, which is swivelcd upon a stud J2, riveted in the base I and formed with a ringer-piece J S, by means of which it is operated against the tension of the coiled operating-spring J".

To assist in preventing the bell from rattling, I provide it with an antirattlin g lever K, which is pivotally mounted upon astud K', located toward the end of the rack J of the operating-lever J. The inner end of this lever K is formed with an operating-bevel K2 and a stop-linger K, arranged to engage with a iixed point, such as the base of the gongstnd, so as to throw the said end of the lever outward toward the pinion IIB, with which the lever is adapted to interlock by its provision with a notch K. Then the operatin glever is drawn by the spring J1 back into its normal position, the bevel K2 of the antirattling lever engages with the gong-stud and moves the outer end of the said lever outward and iinally engages and interlocks it with the pinion. Just at this time the stopfinger II3 of the antirattling lever engages with the gong-stud and brings the movement of the operating-lever J to a stop. It will thus be seen that here the said stop-ringer takes the place of a stop-pin for the operating-lever, which is stopped while still under the tension of the operating-spring J", the tension of which is therefore communicated through the operating-lever to the antirattling lever, which is maintained in its interlocked position thereby. The operatingspring J" is therefore utilized to lock the train of the bell, so to speak, against movement when the bell is not being operated.

I would have it understood that I do not limit myself to the exact construction herein shown and described. lhns the details of.

the carrier, strikers, and friction-spring may be changed, as well as the details ot the antirattling lever. Furthermore,theantirattling lever is not limited to use in conjunction with such a carrier and with such strikers, and vice versa..

Having fully described my invention, what I claim as new, and desire to secure by Iietters Patent, is-

l. In a portable bell, the combination with a sheet-metal carrier adapted to be rotated and provided with striker-lug slots, of llat, slug-like strikers mounted upon the ends of the said carrier, and having integral oblong lugs depending below their lower faces for entrance int-o the said slots,sheet1netal straps made independently of and mounted in the ends et the carrier for embracing the said. lugs, and a friction-spring, the ends of which are entered into the said straps and engaged with the upper faces of the strikers.

2. In a portable bell, the combination with a sheet-metal carrier adapted to be rotated, and formed with longitudinallyarranged striker-lug slots, ol flat, slug-like strikers upset to form integral depending oblong` lugs entering the said slots, two straps made independently of and applied to the respective ends of the carrier and embracing the said strikers, and a friction-spring engaging with the upper faces ot the strikers, entered i nto the upper ends of the said straps, and having its said ends cut to form a plurality of springilngers which are reversely bent tor bearing upon the straps and strikers.

In a portable bell, one or more sheetmetal strikers formed with depending longi` tudinally-arranged integral oblong lugs produced by a partial shearing of; the centers of. the striker-blanks, whereby recesses exactly corresponding in dimensions to the said lugs are formed in the upper faces of the strikers.

t. In a portable bell, the combination with an operating-lever termed with a segmental rack, of a pinion into which the said rack meshes, a spring connected with the said lever tor operating it in one direction, and an antirattling lever pivotally mounted upon the operating-lever, and adapted to be engaged with a iixed point so as to be thrown outward to interlock with the pinion when the operatinglever is brought into its normal position, the antirattling lever being held in its locking position bythe tension of the said spring.

5. In a portable bell, the combination with an operatii1g-lever,an operating-spring therefor, and an antirattling lever pivotally mount ed upon the said operating-lever and held in its operating position bythe tension of. the operating-spring when the operating-lever is in its normal position.

G. In a portable bell, the combination with the gong-post thereof, ot an operatingdever formed with a segmental rack, an operatingspring connected with the said lever, and an anti rattling lever pivotally Ymounted upon IOO TIO

the operating-lever andformed with an op-v speeieation inthe presence of two subscriberating-nger and a stop-linger which eoaets ing witnesses. with the gong-stud, the said antirattling lever being engaged with a member of the bell f vHERBERT S PULLMAN' 5 for locking the same against rattling when Witnesses:

the bell is in its normal adjustment. v M. L. SPERRY,
